Long-term Survival in Endometrial Cancer with Special Reference to Age as a Prognostic Factor

Abstract

Long-term survival was evaluated in 13 586 patients with cancer of the endometrium, constituting 97% of all cases diagnosed in Sweden 1960–1978. Survival rates corrected for the expected mortality revealed that age at diagnosis is an important predictor of prognosis, with a constant trend towards a more favourable course in younger women. Thus, the cumulative relative 15-year survival rates ± 95% confidence limits were 90 (86.1–93.7)%, 89 (87.4–91.3)%, 72 (68.9–74.3)%, 50 (44.9–54.7)% and 32 (18.3–45.6)% at ages 35–44, 45–54, 55–64, 65–74 and 75+ years respectively. Patients younger than 55 years deviated from the general pattern by having an excellent survival and virtually no excess mortality after 7 years of observation.
